Product Details

Product Description:

GFRP rock bolts are designed to provide stability and support for rock masses, tunnels, slopes and other underground or excavated structures; The surrounding rock mass is bonded. Under the interaction between the FRP bolt and the surrounding rock, the stress state of the surrounding rock is changed, the overall stiffness of the rock mass is improved, and the deformation resistance and bearing capacity of the rock mass are enhanced.

We can produce solid GFRP rock bolts and hollow GFRP rock bolts to meet your different requirements.

Feature:

1. FRP tray nuts are generally pressed or molded, with good sealing performance and durability, and generally do not need to be coated with anti-corrosion paint;

2. Corrosion resistance, light weight, high tensile strength, easy maintenance and long service life;

3. Flame retardant, non-conductive and heat-insulating, easy to cut;

4. Widely used in equipment and pipeline systems in shipbuilding, automobile, chemical industry, electric power and other industries, especially when used in harsh environments such as humidity and corrosion, it has better performance advantages;

Fiberglass bolts and anchors for slope and face stabilization

Fiberglass bolts and anchors are reinforcement materials used for stabilizing slopes and working faces. They are made of high-strength fiberglass and resin, and have excellent corrosion resistance, tensile and shear strength. Fiberglass bolts are mainly used for support and reinforcement in geotechnical engineering. They are usually fixed in rocks or soil mounds by drilling holes, and the reinforced support system is connected with bolts to prevent landslides and landslides. They can be used outdoors and indoors, and are easy to install and remove. Fiberglass anchors are similar to bolts, but they are embedded directly into the ground for reinforcement. This reinforcement method is suitable for underground coal mines and tunnel engineering, and can improve the stability and safety of geological engineering. Compared with steel anchors, fiberglass anchors have the advantages of light weight, high strength and corrosion resistance, while reducing construction and maintenance costs. It should be noted that when selecting and using fiberglass bolts and anchors, it is necessary to consider the actual working conditions and support needs, select models and specifications reasonably, and construct in accordance with relevant requirements and standards during installation and use to ensure that they are Stable and safe.
